When you build a backyard shower next door to a 25-story apartment building in downtown Toronto, questions are going to arise. Like, how can it possibly feel private?

Cue the huge maple trees. They ring this shower, providing a canopy of shade—and discretion. The shower's stacked-slat walls—reclaimed hemlock, from a farmyard pen—allow air to circulate and create natural support for cantilevered ledges. Designer James Dale of Toronto-based Earth Inc., who says he has a propensity to "talk back but later apologize," says: "It's very urban, but there's a park nearby, and we wanted to bring that feel into the backyard." Here's how to get the leafy look:

Above: After laying a limestone floor, Dale used leftover "dinner plate" stones as shelving. "Basically, gravity will hold it in," he said. To see a selection of landscape stones, visit Golden Isles Granite.

Above: An alternative to traditional pillar candles, Flameless Wax Candles run on batteries; a little water won't snuff them out. They're $12.50 to $34.50, depending on size, from Pottery Barn.

Above: Dale used vintage plumbing. "These were Victorian designed faucets and brass heads, where all the pieces had been refinished," he said. For a similar look, the Cheviot Claw Foot Tub Shower kit also has a faucet, to rinse sand off your feet; it's $529.99 to $753.99, depending on finish, at Vintage Tub. In a cold climate, disconnect the water lines each winter to thwart pipe-bursting freezes.
